Scientists Believe Earth Was Purple 2.4 Billion Years Ago. Here's What It Means For Future
The Purple Earth Hypothesis has significant implications for the search for life on other planets.

Moon Is Rusting: Scientists Stunned By Hematite Discovery On Lunar Surface
Understanding of rusting could impact future lunar missions, resource utilisation and equipment design.

Earth’s Oxygen Explains Mysterious Rust Formation on the Moon
Despite lacking air and water, the Moon hosts hematite—an oxidized iron mineral. Scientists discovered Earth’s escaping oxygen drives this rusting process during the Moon’s passage through the magnetotail. Observations from Chandrayaan-1 and NASA’s Lunar Reconnaissance Orbiter confirm hematite patches where Earth wind suppresses hydrogen an...

Earth's Slowing Rotation May Explain Rise Of Oxygen In Atmosphere, Study Finds
The study highlights how longer days allowed cyanobacteria to photosynthesise more oxygen because their activity depends not just on sunlight but on the timing of their metabolic processes.

Scientists Explore Role of Space Radiation in Powering Alien Microbial Life
A new study proposes that life may exist far from sunlight in a “radiolytic habitable zone” deep beneath the icy surfaces of Mars, Europa, and Enceladus. Cosmic rays, which can penetrate rock and ice, break water molecules apart to release hydrogen, oxygen, and energy-rich electrons. These can fuel microbes in subsurface water, much like bacter...

Researchers Study Prehistoric CO2 Levels After Reconstructing Air From Dinosaur Teeth
This innovative approach has shed new light on the prehistoric atmosphere and Earth's climate history.

Exclusive - 'Would Not Have Allowed Axiom Launch If Issues Weren't Fixed': ISRO Chief
Group Captain Shubhanshu Shukla has returned to Earth after spending 18 days at the International Space Station. He became the second Indian after Wing Commander Rakesh Sharma to go to space since 1984 and the first Indian to go to the space station.

Earth Will Lose Its Oxygen: Scientists Warn Of A Rapid Countdown
The findings also suggest oxygen may not be a permanent biosignature on habitable planets, impacting the search for extraterrestrial life.

Scientists Predict Exact Date Life On Earth Will End: Study
A supercomputer simulation predicts that life on Earth will end in 1 billion years due to the depletion of oxygen caused by the Sun's increasing heat and brightness, ultimately rendering the planet uninhabitable.
